Certified Rhythm Analysis Technician (CRAT) Practice Exam

To begin remote cardiac device monitoring, batteries are essential tools because they provide the necessary power for the devices to operate and communicate data. Cardiac monitors, such as implantable devices or external monitors, rely on batteries to ensure continuous functionality, data collection, and transmission to healthcare providers. Without adequate power supply from batteries, the devices would not be able to perform their monitoring tasks effectively or send information about the patient's heart health to the monitoring system. This is crucial for timely interventions and ongoing patient care management.

While electrodes, rubber bands, and adhesive tape may play roles in other contexts of cardiovascular monitoring, they do not serve as the primary means to initiate remote monitoring of cardiac devices. Therefore, only batteries are fundamentally required to support the function of these monitoring systems right from the start.
